The first Mustangs were considered 1965 models by Ford, even though production started in March of 1964, resulting in an 18 month production time for the '65.
The start of the 2nd production run of the 65 Mustang was Aug 17, 1964. Cars built before that date are now referred to as "1964 1/2."

1964-1/2. The grille of a "64 1/2" is nearly identical to the 2nd production run 65. The 64 1/2 pictured here has the chrome strip on the hood lip (just under the F-O-R-D letters). This may be a hood from a '65 (2nd production run). If you have a photo of a "64 1/2", please click "Contact" above.
